Time to answer some questions!Can you try to run it with two PCIe connectors per board? It would be interesting to see if it needs all three.
The miner won't operate with two PCI-e connectors per board, according to Bitmain. See this image:

Thanks for posting this, but i find Bitmain's instructions on imgur's image ^^^ incomprehensible as it is a mishmash of S5+ and S7, especially point #5 where it mixes S5+ and S7 together. Also, why 16A for S7 when it is 1210W, which is 11A even at the lowest 110V. This is a question to Bitmain, of course.
